DE Bio -- Glycolysis

What goes into glycolysis?

1 glucose

What is glucose’s molecular structure?

C6H12O6

What is the first step of glycolysis?

Invest 1 ATP —> ADP + P + energy

What happens next?

Phosphorylate 6th C of Glucose molecule

What new molecule is formed?

Glucose 6-P

What happens to the Glucose 6-P?

Isomerization

What new molecule is formed from the isomerization?

Fructose 6-P

What happens next?

Invest 1 ATP —> ADP + P + energy

What happens to the Fructose 6-P?

1st C is phosphorylated

What molecule forms after Fructose 6-P is phosphorylated?

Fructose 1

What happens to the Fructose 1

6-P?

What happens to the DHAP?

Isomerization into G-3-P
